ALEXANDER BUCHHOLZ, OF JANESVILLE, WISCONSIN.

- IMPROVEMENT IN WHEELS FOR VEHICLES.

Specification forming part of Letters Patent No. 145,393, dated Dcccmbcr9, 1873; application filed September 25, 1873.

To all whom it may concern Be it known that I, ALEX. BUoHHoLz, of Janesville, in the county of Rock and in the State of Wisconsin, haveinvented certain new and useful Improvements in WVagon-WVheels; and dohereby declare that the following is a full,'clear, and exactdescription thereof, ref= erence being had to the accompanying drawings'making a part of this specification, in which-- Figure 1 is aperspective view of the central portion of one side of a wheelcontaining my improvements. Fig. 2 is a like view of the op posite sideof said center, the flange or collar being broken away and two spokesremoved so as to show the lugs of the opposite flange. Fig. 3 is acentral section of said wheel-center upon a line with its plane ofmotion, and Fig. 4 is a like view upon a line having a right angle tosaid plane.

Letters of like name and kind refer to like The design of my inventionis to produce a stronger, better, and more durable connection betweenthe spokes and hub of a wheel; and it consists, principally, in thepeculiar shape of the contiguous edges of the spokes and theircombination, with the lozenge-shaped lugs, with one of the metalcollars, substantially as and for the purpose hereinafter specified.

In the annexed drawings, A represents the hub of my wheel provided witha series of equidistant radial mortises, a, into each of which is fittedthe corresponding tenon b of a spoke,

, B, in the usual manner. From the periphery of the mortised portion ofthe hub A the contiguous edges of the spokes B extend outward uponradial lines, and within each edge is formed a recess or notch, which,combined with the corresponding opposite notch of the adjacent spoke,forms a diamond or lozenge shaped opening, I), that extends horizontallythrough said spokes, and has its longitudinal axis upon a radial line.Upon each end of the hub A is placed a flanged collar, 0, which closelyembraces the periphery of said hub an d closely fit into, the openings1;, said lugs hav- 4 ing such length as to cause them to nearly meet theinner face of the opposite flange. A

rod, D, passed through suitable openings in the flanges and eachalternate lug, is provided upon one end with a head, (I, and upon itsopposite threaded end with a nut, d, by means of which said flanges maybe drawn closely against the sides of the spokes. If desired, the nut (1may be dispensed with. and the end of the rod riveted down upon itsflange. In order that the positions of the flanged collars 0 may beinsured longitudinallyupon the hub the opening through each is reducedin size near its outer end so as to form a shoulder, c, which fitsagainst a corresponding shoulder, a, formed upon said hub when saidcollar is drawn to place.

The parts thus constructed and combined possess more than ordinarystrength, it being impossible for the spokes to move in any directionwithin their hub; and, while possessing such advantages, saidconstruction does not increase materially the cost of a wheel.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1s- The notched and tenoned spokes B, fitted within themortised wooden hub-core A, and forming, between their contiguous edges,the openings 1), in combination with the flanged collars O and O, thelatter of which is provided with the lugs c and c, substantially as andfor the purpose specified.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of September, 1873.

ALEXANDER BUOHHOLZ.
